A logo is a design, graphical representation, image or symbol that represents a business or organization. Logos were initially used to distinguish and differentiate products, the logos assisted purchasers in finding the product they prefer or have come to trust (or not trust). When product selections were limited and items were marked with a logo which a consumer was familiar they would naturally assume a certain level of quality or value, even if they had not previously used that specific product from that vendor. Now many companies not only have a corporate logo, but they have a logo to represent each of their products or product lines.
